there are some transcribed records for the parish on FreeReg
http://www.freereg.org.uk/From reading his will, I would say Morgan didn't marry as he makes no provision for family closer than his brothers. Age given on his burial in 1839 is 49, Richard was given as 73 on his burial in 1831 and Magdalen as 74 at her burial in 1833.
Mary Morgan married Thomas Pugh 10/8/1832.
I think the abode for John may begin with F.
